COMPARISONS OF THE SKELETONS OF HORSE AND MAN 



Bone for bone, the two skeletons are like one another, though man is a biped and the horse 

 a quadruped. The backbone in man is mainly vertical; the backbone in the horse is horizontal 

 except in the neck and the tail. Man's skull is mainly in a line with the backbone; the horse's at 

 an angle to it. Both roan and horse have seven neck vertebrae. Man has five digits on each 

 limb; the horse has only one digit well developed on each limb.
